|The THM-Carbones Scapula is a carbon fork for racers. It combines exceptional cornering precision and stiffness with very low weight. With its combination of properties and great reliability the Scapula is the right answer to the enormous demands of modern road racing. The lateral stiffness means the fork will not yield under out-of-the-saddle hammering. Fore-aft stiffness, important when braking hard, is at previously unknown levels.|
The secret behind every Scapula fork's performance is in the continuous carbon fibers all the way from the steerer down to the dropouts. Even the dropouts have a carbon fiber core. The wall thickness of steerer and fork legs varies continuously to provide an optimal stiffness-to-weight ratio. The Scapulas elliptical interior shape is perfect to take on both large forces from direct-on hits as well as side loads. Minute attention to detail during the optimization process lead to sensationally low weight combined with superior stiffness.
Features of the THM-Carbones Scapula:
- Continuous fiber orientation
The THM-Carbones Scapula main carbon fibers run uninterrupted all the way from the top of the steerer down to the dropouts, allowing maximum stiffness and durability at a very low weight. Common carbon fiber forks are made from several parts glued together (e.g. steerer, fork legs, crown, dropouts). In addition, all THM-Carbones Scapula forks use a special kind of fibers. They do come at a higher price, but their superior strength and the resulting doubled stiffness compared to ordinary carbon fiber forks make them the obvious choice for our forks.
- Varying wall thickness
In all parts of the Scapula fork, wall thickness and direction of the carbon fibers are carefully chosen depending on the kinds of forces encountered in actual riding conditions. The interior cross-section of the steerer tube, for example is oval instead of round, as the greatest forces a fork is subjected to are from the front. Thus, the “Scapula” forks are both stiffer AND lighter than competitors’ forks with ordinary round steerers.
- Aluminum crown race
The lower headset race sits on an aluminum sleeve bonded to the carbon fiber fork crown. Compared to a carbon fiber headset seat, the aluminum sleeve provides a more exact alignment of the headset race and will keep its shape better even after multiple headset changes.
- Protected brake mount
The bolt holding the front brake is fixed securely in an insert made from hardened aluminum. Thus, the bolt is not in direct contact with the carbon fiber. The fibers are securely protected, and forces are distributed evenly.
- No star-fangled nut in the steerer
There is no need for a crude clamping mechanism with the Scapula. The upper section of the steerer tube has been fitted with large threads. Simply cut the fork to length and insert the supplied adapter. Headset adjustments are made using an ordinary M6 bolt.
Ordinary designs use a sharp-edged star-fangled nut which is hammered into the steerer or a wedge-type expander. Both designs increase weight and diminish longevity. Not so with Scapula!
- Carbon fiber dropouts
For weight reasons, the dropouts of the THM-Carbones Scapula have a carbon fiber core. Aluminum inserts protect the dropout against compression by the axle and quick release. Together, the construction yields a sensationally light part which is fully capable of standing up to every day racing use.
